A3.7/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden and it does disclose the key operating bounds (default 30 lines, hard max of 200), which is genuinely useful. It does not say whether lines come back oldest-first or newest-first, whether the channel must be joined, or what happens for an unknown or empty channel.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence with the resource first and the numeric bounds in parentheses; every clause carries information and there is no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read tool with three optional parameters and no output schema, this covers the essentials: what is returned, from where, and the size limits. A brief note on result ordering would make it fully complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 67%, and the description fills the most important gap by stating the 'lines' default of 30 — a value the schema omits (it only declares min 1 / max 200). The 'channel' default is already documented in the schema, and 'format' is fully documented there, so nothing critical is missing.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description gives a specific verb and resource — returning the last N lines of a channel — plus the default and cap. Saying 'of a channel' implicitly separates it from the dm_history sibling, though it never names that sibling directly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is only implied: an agent can infer this is for channel scrollback rather than DMs from the word 'channel', but there is no explicit when-to-use or when-not-to-use guidance, and no mention of how it relates to dm_history, listen, or await_answer.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
